A potentiometer circuit is set up as shown The potenti gradient across the potentiometer wire is k volt cm an the ammeter present in the circuit reads 1 0 A when th two way key is switched off The balance points whe the key between the terminals i 1 and 2 ii 1 and 3 plugged in are found to be at lengths 1 em and la cr respectively The magnitudes of the resistors R and in ohm are then equal respectively to A DA www R wwwww X 1 k 12 1 and kl 2 kly and k l2 4 3 k l2 1 and kl 4 kl and kl B
